From what I read it was by the Heisenberg uncertainty principle but I don’t understand how, too technical for me when I read up on the topic

LaPlace’s demon is a thought experiment if some creature/intelligence that has knowledge of the speed and position of every particle in the universe. Thus, this creature could predict anything that happens. It’s not about data storage or something like that, in this thought experiment the calculation power to predict the future based on the knowledge I described above is there.
Basically you answered your owm question in your post. The problem is you physically simply cannot know the position and the speed (i.e. energy level) of any one particle at the same time. That’s what Heisenberg’s uncertainty is all about. Since it’s impossible to determine both the position and the speed of particles at the same time, the whole thought experiment crumbles. Sure you could say that in the experiment it’s possible to do so but that would be breaking the laws of physics.
